Preparation includes fasting for around 12 hours, following bowel prep if advised, and informing your clinician about medications, conditions, or devices.
June 14, 2026

Capsule endoscopy is a diagnostic test used to examine the small intestine. It involves swallowing a small capsule containing a camera, which takes images as it moves naturally through the digestive system. The capsule is later passed in your stool.

What is Capsule Endoscopy?

Capsule endoscopy is used to investigate areas of the small bowel that cannot be easily reached using traditional endoscopy or colonoscopy. It helps identify issues such as unexplained bleeding, inflammation, or other abnormalities in the digestive tract.

The capsule contains a tiny camera, light, and transmitter that sends images to a recording device worn by the patient.

How the Test Works

The procedure is simple and does not require sedation.

You will:

  • Swallow the capsule with water
  • Wear a small recording device during the test
  • Go about most normal daily activities while the capsule moves through your digestive system
  • Pass the capsule naturally in your stool, usually within 24 hours

The images recorded are later reviewed by a specialist.

Preparation for Capsule Endoscopy

To ensure clear results, preparation may include:

  • Fasting for around 12 hours before the test
  • Following any bowel preparation instructions provided by your clinician
  • Informing your healthcare provider about any medications, medical conditions, or implanted devices such as pacemakers
  • Avoiding certain activities as advised during the test period

Your clinician will give specific instructions based on your individual case.

What to Expect During and After

The capsule is painless to swallow and does not cause discomfort as it travels through the digestive system.

During the test:

  • You should avoid MRI scans until the capsule has passed
  • You may be advised to avoid strenuous exercise
  • You may need to wait before eating after swallowing the capsule

After the test:

  • The recording device is returned to the clinic
  • The images are reviewed by a specialist
  • Results are usually available within a few days to a week
